A local tire place charged me $5 for filling four when I purchased them.

 

Miniclubman is probably correct in the science world but in the real world my tire pressure warning did not go off when the temperture dropped to the 30's last night. I will just stick with the nitrogen in my tires.

Actually, if you have nitrogen in your tires, the jet fuel inside of them is much likely to burst into flames in the event of a crash landing.

 

I was quoted $75 for a nitrogen fill at my dealership!

 

Yes, all laws of physics are temporarily suspended whenever you turn the key on your MINI.

 

Nitrogen does not contain any nitro (or jet fuel).

If you are a Costco member (highly recommend that), they have free nitrogen fill at their auto centers.

Your TPM's might last longer with a dry nitrogen fill, as the oxygen in compressed air contributes to corrosion.

 

No sense of humor.

I'm running runflats too. If you have a 2nd gen. MCS, I believe it should read 33 psi all around. Maybe you're misreading the label?

 

But some of us enjoyed it, Fishbert!

 

Well, I got in my car this morning, and apparently during the night, Mini gremlins got into my computer and fixed the dad gum thing. I clicked on SET/INFO, then to the flat tire symbol, and sure enough, under the symbol there was a "resetting" arrow. I clicked on it and held it for about 30 seconds, then drove away. Two blocks down the road and the flat tire symbol was gone......everytning back to normal. Thanks for all your help, I was really worried that I might have to go to atlanta(120 miles) to the nearest dealership to correct this, but wala.....it's fixed on it's own, and now I know how to deal with it when/if it happens again.

 

33 psi for 16" rims
38 psi for 17" rims (MCS with sport package will have a different label on the door)

Glad your problems are solved.

 

My MCS w/17" crowners shows 38 on the label. I hate the RF's and reduced the pressure to about 34 all the way around, better ride for sure. Reset the TPMS and all is well.

 

I had to fix one of my tires last week... Did the reset once the light came on... it did not work. Checked tire pressure once again and did the reset, and the light is still on... Question... Is there a 'special' way to put the tire back on after it has been repaired? Should've i asked them to do something with the rim in order for the tire pressure light to work properly...? I'm confused and the manual doesn't say much...

 

Are all your tires set for about the same psi cold? Once you reset it you have to drive a few miles.

 

Mine comes on and then goes off every few days or so. Tire pressure is correct. I have just come to accept it as a slightly annoying bug.
